Researching of Vietnam Prehistory

Based on my researching of Chinese Classical Astronomy and Text, this book is the latter version of the former "A New Approach on Old Issues Of Ancient Vietnamese History" - ISBN 9781310245367. The new name is "Researching of Vietnam Prehistory", ISBN 9781370154548. By accessing and comparing vocabularies in the Sino-Tibetan and Austronesian languages, locating them in genetic maps with archaeological, cultural and bibliographic adjustments, we have figured out the meaning of important terms intimate to ancient Vietnamese history as presented below:1.
Vi?t ? and Âu ? are homophones in the Han Dynasty and before, serving as transcriptions of Jiang - Zhe words by Chinese characters; originally and literally they mean water or water area, and their derivative sense is Country. They are similar to the word Qu?c, which means earth/land/soil, and the derivative meaning of which is Country. Accordingly it can be inferred that Vietnam means Southern Country or Southern Land.2.
L?c ? is equivalent and has a birth process similar to that of Vi?t and Âu, but belongs to the Tai-Kadai linguistic sphere, which matches the northeast region of the present Tai-Kadai language map. Âu L?c was formed as a result of the combination of Âu and L?c. It was also the indigenous name of the kingdom of Nam Vi?t founded by Tri?u Dà. L?c Vuong, therefore, means the king of the country; L?c H?u - the Marquess; L?c Dân - The People of the country; but L?c Di?n should be understood as paddy field, rather than country's field.3.
Hung King ?? is a word created at a much later time than Lac King ??, its element Quân ? simply refers to the Chief of the nation/tribe whether of Âu Vi?t or L?c Vi?t origins. Hùng King as a term is similar to the Yan and Huang emperors of China, or, in a more specific and understandable comparison, equivalent to the Founding Fathers of America. This book also affirms that Nan Jiao ?? , Jiao Zhi ?? , Xiang Jun ?? , Jiu Zhen ??, and Ri Nan ?? are united concepts related to Chinese Classical Astronomy.
While researching the meaning of Nan Jiao, Jiao Zhi, Xiang Jun, Jiu Zhen, and Rinan by using Chinese ancient astronomy, we accidentally figured out the non-superstitious meaning and how to establish the definitions of River Map ??, Lo Shu Square ??, Yin Yang ??, Five Elements ?? and Yijing ??. According to the author, this might be the first time ever in the history of East Asia that the Chinese mysterious "holy grail" was discovered by using scientific method.
Due to the digression of the book's subject, the references are rough but they are more plausible and reliable than any illusory story that was put on the establishment of River Map, Lo Shu Square, Yin Yang, Five Elements, and Yijing. The first meaning of Jiao Zhi ?? is the southern region located next to Nan Jiao??. Next, Jiao Zhi ?? refers to a southern region sharing the border with the Chinese Empire.
Within thousand years of southern expansion by different reigns, Jiaozhi located in Hubei of Western Zhou ??. Before 239 BC, Jiaozhi located between Hunan and Guizhou. Until Eastern Han ?? time, Jiaozhi was officially appeared on the Chinese map as a province Jiaozhibu ??? including Jiaozhi district ??? and eight other districts. During the reign of Qin ?, Jiaozhi was Xiangjun ??. The Xiangjun region was confirmed as Jiaozhi by meaning and by astronomical pre-observation.
Jiuzhen ?? means "the root of the sun" which is similar to the Equator. Rinan ?? (Sun south) means the southern region of the sun. In Rinan, the gnomon's shadow is always located in the south, which is the Southern hemisphere from Tropic of Capricorn to South Pole. The above terms' meanings will change the important details of China's southern provincial history as well as Vietnam's.
